  • Patent number: 10609976
    Abstract: A quick wearing tool for a pair of magnetic eyelashes members, which includes a handle, a clip unit, an upper clip plate connected to a top end of the clip unit; and a lower clip plate moveable connected to the handle allowing upward and downward movement. The two clip plates have a magnetic polarity opposite to the magnetic eyelashes members, are made of iron materials or magnetic materials for forming a magnetic loop with the magnetic eyelashes members. The magnetic properties of the two clip plates are lower than that of the magnetic eyelashes members, therefore the magnetic eyelashes members are pre-loaded onto the two clip plates through magnetic attraction and then detached from the two clip plates to secure into position on real eyelashes by attraction between the two eyelashes members when the lower clip plate is moved upward towards the upper clip plate.
